What diameter free flow system ???

[Seatfsi]

Hi guys ,I have a 2.0litre f.s.i. Seat Altea. It has a branch but I need a new exhaust and I need advice...should I fit a 50 mm free flow or a 57mm

Depends what u want. Any head work done? Is it stock?

[Seatfsi]

It's stock standard

Not sure what the other guys will recommend. I'd say on a stock 2.0 go 50mil.

Just my 2cents

Sorry to hijack the thread but now that you ask if at sea level or highveld? Would've different size make difference in this case whether his at sea point or inner land?
